My first project - 1974 CB360 K0
Craizeehair:
Guess who got an ultrasonic cleaner and couldn’t wait to mess about with it!
I set about cleaning a few bits and bobs and had the bright idea of cleaning the rocker cover, it cleaned it ok but it has changed the colour dramatically. My question tho those who know is, if a this still ok to use… The journals are in the same condition but no longer bright, will this matter, will the integrity of the part be compromised? I do have a spare which has a ok but not quite as good as this one.

Any fluid / additive that is mildly caustic based, causes alloy to go black. It can also wear alloy away and make it porus, depending on how long it was immersed for.
McCabe-Thiele (Ted):
As Julie said it looks like something caustic has discoloured the alluminium - much like a dishwasher does if you put an alluminium sauspan in by mistake. (Guilty)
If its light staining as opposed to surface corrosion it might not be an issue.
I use the Allendale Cleaning Solution for Alluminium parts like carbs etc.
Bryanj:
Should be ok to use, just not pretty
Craizeehair:
Thanks all, lesson learned.
